HAYSTACKER.

Application filed September 26, 1922. Serial No. 590,700.

To all whom t may concern:

Be it known that I, JAMES O. Arms'ro'rfr, a citizen of the UnitedStates, residing at Pauls Valley, in the county of Garvin and T:ita-teof Oklahoma, have invented certain new and useful Improvements inHaystaclrers, of which the following is a specification.

My said invention relates to a hay stacker and it is an object of theinvention to prolvide a device of this character which shall be arrangedto receive the hay directly from the field and build up a stack of anypreferred size and shape to protect the hay against the weather.V

Another object of the invention is to provide a device of this characterwhich may feed the hay directly to a press.

Still another object is to provide a ma chine which can readily betransported from one place to another.

Another object is to effect economy of labor, as with my device two mencan do the Work of stacking about ten tons of hay per hour, and can makea better and more uniform stack than the average handmade one.

Referring to the accompanying drawings which are made a art hereof andon which similar reference ciiaracters indicate similar parts, 1 f

Figure 1 is a plan of my machine,

Figure 2 a section on line 2 2 of Figure 1,

Figure 3 a transverse section on line 3 m3 of Figure 1,

Figure 4 a transverse section on line 4-4 of Figure 1, and

Figure 5 shows the device arranged to feed a pair of baling presses.

In the drawings reference character l() indicates the main frame of thedevice, this frame constituting a truck having front wheels 11 and rearwheels 12. The front wheels are mounted on an axle 13 pivotallyconnected to a bolster on the frame 10 to permit the front wagon to.turn. A pair of wheels 14 are mounted on an axle forming a rear truckwhich is pivotally connected lt 15 to the rear axle of the front wagonby means of a telescoping connection 16. The rear truck supports aconveyor and a stacking device, the conveyor being located to receivehay from a conveyor on the front truck.

The front truck supports, by means of the frame 10, a air of foldingreceiving devices or aprons 1 and 18 adapted to lie on the ground asshown at the front of Figure 1 and at the right in Figure 3, or to beraised into the position shown at the rear of F igure 1 and at the right`in Figure 3. The aprons are adaptedto receive hay from a buck rake, thedraft animals passing one onV each side of an apron and the rake slidingover the same. The rake is then backed off and the hay is left on theapron. A set of pins or teeth 19 on each apron acts to hold the hay inplace and prevent its withdrawal by the rake as it is backed off. Itwill be understood that grain may be similarly placed on the aprons by aheader barge or bundles of grain or fodder may be carried to it by anyconvenient means. A U-shaped holding device 20 pivoted to the side ofthe frame 10 above the apron is adapted-t0 be lowered into holdingposition relative to the material on the same. The holding device hasteeth 21 adapted to penetrate the hay or other material and these teethcooperate with teeth 19 to hinder removal of the hay.

For raising the aprons into the vertical position each of them isprovided with a pair of pulleys 22 adjacent its free end. In a preferredarrangement of the device a cable 23 is adapted to be wound on a drum24, the cable passing from the drum to a pulley 26 on a fixed member ofthe frame, here shown as a longitudinal bar 27 forming one of the topbars of the frame. From the pulley 26 the cable passes to a pulley 22 onthe receiving device 177 then in succession to a pair of pulleys 28 and28 on the bar 27, then to another' pulley 22 on the receiving device 17and then to an at` taching device at 29 on the bar 27 or on some otherfixed part of the frame. The cable 23 for the left-hand apron issimilarly arranged and is wound at one end on a drum 25. The drums 24and 25 ire loosely mounted on a shaft 30 and are adapted to be clutchedthereto respectively by means of a pair of clutch levers 31 and 32.Adjacent to the clutch levers I provide a pair of pivoted levers 33 and34 connected to the clutch levers by links35 and 36. The levers 3-3 andV3ft project at their free ends into the path of movement of thereceiving devices 17 and 13 and provide automatic means for unclut-chingthe respective drums from the driving shaft when the receiving devicesare raised to their full extent. Each of the clutch levers is adaptedand intended tobe thrown out by hand when the receiving device is highenough but this automatic means prevents injury to the machine shouldthe operator for any reason fail to disconnect the clutch at the propertime. The manual control is essential for the reason that the hay orother material will often he in a dense, thiclr mass preventingthe apronfrom being raised to its full cxtent and interfering with the operationof other parts, hence the elevating movement` should be stopped one ormore times before theA limit is reached.

The shaft 30l carries a gear 37 driven by a pinion `38 on Va shaft 39VWhich carries a pulley 40 driven by a belt operated in any convenientma'nner` as by a steam orv gasoline engine. y v

For removing the 4hay from the elevated aprons Iprovide al revolvingcylinder 4l -having a plurality of horns42. Each of these horns is madein the form of an anchor having a shaft 43 extending through thecylinder and secured bya nut 4A or equivalent means and the shaftsupports a. pair of oppositely extending horns spreading gradually awayfrom the cylinder whereby one of each pair of the said horns is adaptedto engage the hay on the'adjacent apronand pullit away When the cylinderis revolved in one direction and the other of each pair is adapted toengage the hay on the other apron When the cylinder `is revolved in theopposite direction. lt will be seen that the immediate removal of all ofthe hay is to some extent prevented by the ttshaped holding device 2Oand by teeth 19 and 2l. Furthermore the aprons are not lifted to theirfull extent when they are heavily loaded or if the material such asshould be thoroughly pulled apart cr is too heavy to'be handled rapidly,as Afor 4example in handling green corn fodder or Wet grass.

F or driving the cylinder l provide a sprocket 45 on the shaft 30adapted to drive a sprocket on a parallel shaft 46 by means of a chainil?. rlhe shaft a6 has a slidable sleeve of conventional type splinedthereto and bearing at its ends a pair of beveled gears e8 and 49adapted to engage selec tively with a. beveled gear 50 fixed to theshaft 5l of the cylinder. 52 serves to slide the sleeve and shift thegears 'to drive the cylinder in one direction or the other. Inemergencies l may take hay or the like from both receiving devices 1,7and i8 at the same time,l the cyl inder revolving in either directionfor this purpose. The capacity of the cylinder to rotate in eitherdirection is also useful inV case the material 'hangs on the horns Whenthe cylinder may be made to rotate reversely, thus causing the adheringmaterial to be pulled off 'the horns. One man should operate the levers3l, 32 and 52 and in general take care of the machine, excepting thoseparts controlled by the man on the stack. y

vUnderneath the `cylinder 41 is a belt conveyor 53 supported and drivenby a pair of shafts :ist land 55. The forward one of said shafts isdriven from the shaft 30hy means of asprocket chain 56. The conveyorbelt revolves in va direction to carry the material. deposited thereonby the cylinder toward the rear of the machine and the material passesfrom this conveyor belt to an elevating conveyor 57 mountedon a rigidframe pivoted tothe front Wagon.

A short auxiliary conveyor 58 yis located adjacent the point of transferto hold down the material and insure `its proper passage A shiftinglever from one legof the main conveyor to the other, this conveyor beingmounted on a frame 53" pivoted at itsrear end. This is especiallyimportant if thehay is very light and` grizzly. This auxiliary conveyoralso helps to pull the hay off from conveyor belt and pushes it along oncon veyor belt 57. The elevating conveyor is supported on the rear truckby means of a pair of bars 59 pivotally connected to the sides of thepivoted supporting ,frame and to the axle of the truclr. The truck alsocomprises a bolster 60, braces 6l for the saine extending diagonallyupward and horizontal braces 62 connected at their ends to the axle ofthe truclr. Each brace at'its forward end is attached to one of thetelescoping elements of the connecting link 16 between the trucks. A

The connecting` link is formed of tivo or more telescoping parts, thesmallest part beingindicated at 63, and the parts are held together inworking position as indicated in full lines in lFigure 2 by aV pin6dpassing through registering openings in each of them. lWhen the deviceis to be moved to a distance the truck let which normally is held in theposition shown in full lines by means of a cable 65 wound on a drum onVthe shaft 66 is permitted to recedeLto `the dotted line position byunwinding of the cable Where upon the parts assume the positionsindiinsges? cated in dotted lines'in Figure 2, the elevating conveyorresting near its rear end on the bolster 60. When the device is again tobe placed in operation a crank on shaft 66 is operated to wind the cable65 on the drum on shaft 66 thereby causing the bar 59, due to itspivotal connections, to raise the conveyor support into the positionshown in full lines. At the same time the link 16 is telescoped and thepin 64 inserted to hold it so. When the device is to be moved only ashort distance, as for starting a new stack adjacent to one justcompleted, I may hook a tractor to the front end of the machine and pullit along without lowering the conveyor frame and stacker. fitter movingthe machine, the conveyor may be lowered part way to place thecontrolling devices for the stacker in reach of the man on the stack, orin windy weather to prevent blowing about of the hay. A wind sheet may,of course, be used if preferred and Vthis may be a Vsheet fastened tothe stacker with ropes and staked to the ground to steady it. Y

For driving the elevating conveyor and the upper conveyor 58 I haveprovided connections comprising a belt 67 running over a pulley on shaft54 and another pulley on the shaft 68 at. the lower end of the frame ofthe elevating conveyor. This shaft, as will be seen in Figures l and 2,carries sprockets engaging with the sprocket chains at the sides of theconveyor belt and also has an intermediate pulley for driving a belt 69which in turn drives a belt 70, the purpose of which is hereinafter eX-plained. The shaft 68 also carries an outer pulley 7l which by means ofthe twisted belt 72 drives the auxiliary conveyor belt 58 in theopposite direction from the other conveyor belts whereby its lower runwill move in the same direction as `the upper runs of the belts 58 and57.

The conveyor supporting means at itsP9 outer end carries a support 73for the stacker proper. This stacker consists of a funnel 7d adapted torotate on its axis, the funnel having a. radially extending flange forsupport-ing it on the frame 73. At its under side the flange has gearteeth at 75 engaging with a pinion 76. This pinion is carried by a shaft77 adapted to be clutched te a pulley 78 driven by the belt 70. Theclutch is normally held in by a spring and I have provided a rope 8l fordisconnecting the s me. At the lower end of the funnel a spout or chute79 pivoted at 80. A pair of ropes 82 and 83 are connected to the chute,the rope 82 passing over a pulley 8s aivotally secured to the side ofthe funnel. VBy means of the ropes it will loe seen that the man on thestack can vary the inclination of the chute which may be held at. thedesired inclination by friction of the parts or if this is foundinsulficient I may provide any conventional form of latch or brake forholding it in adjusted position. It will be seen that by graduallymoving the chute lirst in one direction and then in the other a circularstack will be forni-ed consisting of layers of material wound in spiralsfirst outwardly to the edge of the stack and then inwardly toward thecenter. The contour of the stawlr may be changed to produce a bulge, ifdesired, and also to draw in the stack at the top in any conventional orpreferred form. For filling in the middle of the stach or for topping1out or for filling low places when the stach' is built on sidelingground I have provided the clutch on shaft 77. lly throwing out theclutch the rotation of the funnel will be stopped and the hay will allbe delivered at the desired spot. In place of the clutch I may provide apulley to which the belt may be shifted or any other conventional powerdisconnecting means.

In the arrangement illustrated in Figure 5 I have adapted my device tofeed a pair f baling presses. I may either use the entire machine asillustrated in the foregoing figures and position the chute 79 to feeddirectly into the upper end 85 of the chute leading to the baling pressor I may provide a special short conveyor at the rear end of theconveyor 53 for carrying the hay to the press. In either case Ipreferably use a chute comprising the upper end 85 having a singlepassage and the lower end having a pairof branch passages 86 and 87leading respectively to presses indicated conventionally at 88 and 89. Aswinging gate 90 is located in position to close either one of thebranch passages and may be open ated in any conventional or preferredmanner.

t will be obvious to those skilled in the art that many modifications ofmy device may be made without departing from the spirit of theinvention, the tr e scope of which is indicated in the appended claims.For this reason I do not limit myself to the precise embodiment of theinvention shown in the drawings anddescribed in the speci licat-ion butonly as indicated by said claims.
